Write this bit field to enable or issue a command. The Chip Erase and EEPROM Erase commands are started when the command is written. The others enable an erase or write operation. The operation is started by doing a store instruction to an address location.

A change from one command to another must always go through No command (NOCMD) or No operation (NOOP) command to avoid the Command Collision error being set in the ERROR bit field from the NVMCTRL.STATUS register.
